Safely using the DIS 90
Warning
Do the following to avoid electrical shock, fire, or
personal injury:
•
•
•
•
•
Turn the engine off before making any
connections.
Use the DIS 90 only on properly insulated
ignition cables.
Keep the Fluke 98 and the DIS 90 leads away
from rotating parts and engine parts producing
heat.
Thoroughly fix all test leads before doing a road
test.
Read the safety section in the Fluke 98 Users
Manual (from page VI).

Connecting the DIS 90 for measurement
Figure 3 shows a connection example for a 4-cylinder DIS engine.
General connection procedure:
1. Connect the DIS 90 Adapter to the Fluke 98 Automotive
ScopeMeter as shown in Figure 3. Use a ground lead to
connect the COM input on the small connection unit to ground
e.g. battery ground.
2.
Connect the round cable plug of the red secondary pickup
set to the Ignition Adapter box on the input with the red
grommet (connection to the input with the black grommet will
not fit because of different plug pinning!)).
3.
Connect the round cable plug of the black secondary pickup
set to the Ignition Adapter box on the input with the black
grommet. (Connection to the input with the red grommet will
not fit because of different plug pinning!)
4.
Connect the black secondary pickup clamps to the spark
leads with negative polarity and the red secondary pickup
clamps to the spark leads with positive polarity.
You can check the polarities as follows (only possible with
engine running):
a. Use a black or red secondary pickup and clamp it to a
spark lead.
b. If the Fluke 98 displays an upward spark voltage, this
pickup is connected to the correct polarity. If a downward
spark voltage is displayed, the pickup is connected to the
wrong polarity. Then use a pickup with the other color for
this cylinder. Bear in mind that the spark voltage may be
low or not visible due to a defect. Refer to the section
“Indication of wrong polarity connections” on the back of
this sheet.
c. Use the next black or red secondary pickup and repeat
steps a and b until all pickups are connected.

6.
Clamp the remaining pickups on the connecting cable to the
Ignition Adapter unit. See the example for four cylinders in
Figure 3 and for six cylinders in Figure 4. For safety reasons
Figure 4. Connection of the unused pickups (example for six
cylinders)
and to get a reliable measurement result, these unused
pickups must not be left unconnected.
7.
Clamp the Capacitive Secondary Pickup (CAP 90 or
PM9096/001) on a spark lead with negative polarity (black
pickup connected). Clamp it as close as possible to the spark
plug (see figure 4). This cylinder is then displayed as first
cylinder in the parade picture.
Automotive Application Example
Indication of wrong polarity connections
The following is an application example of how to measure a DIS
system (with dual-spark ignition coils) for a 4-cylinder engine. See
Figure 3.
Service and Maintenance
Storing the DIS 90
If you are storing the DIS 90 for an extended period of time, the
battery should be removed and stored separately. To remove the
battery, see Figure 7.

Specifications
FLUKE guarantees the properties expressed in numerical values
with the stated tolerance. Specified non-tolerance numerical values
indicate those that could be nominally expected from the mean of a
range of identical differential voltage probes.
GENERAL
DIS 90 application
Replacing the 9V Battery
Warning
To avoid electrical shock, disconnect the DIS 90 from
the ignition cables before replacing the battery.
Maximum number of cylinders
R
Figure 6. One red (positive) and one black (negative) secondary
pickup swapped (4-cylinder system).
If you connect a pickup to a cable with the wrong polarity, the
ignition pulses of the related cylinder are displayed upside down
and the RPM display is not correct. In the example of Figure 6,
where two out of four pickups are wrongly connected, the RPM
display is half the real value.

Note:
This instrument contains an alkaline battery. Do not
dispose of this battery with other solid waste. Used
batteries should be disposed of by a qualified recycler or
hazardous materials handler. Contact your authorized
FLUKE Service Center for recycling information.
Replace the 9V battery when the ‘BATTERY OK’ LED on the
IGNITION ADAPTER unit remains off when the power is switched
on.
